The light source can be set by the control system to control the light intensity and light on time of each layer of the light source on each group of cultivation racks in the room, which can be infinitely adjusted from 0 to 100%;

8. Airflow circulation structure: The airflow circulation structure supplies air from the side wind wall orifice plate, passes through the cultivation areas on both sides, and returns air from the top of the center to maintain a constant indoor temperature and humidity. A diffuser cover is installed at the inlet of the evaporator to filter and trap unclean air particles in the diffuser cover, preventing them from entering the air duct circulation and improving the cleanliness of the air inside the box. The overall air wall orifice plate has uniform openings and smooth air outlet; The overall wind wall is made of aluminum alloy material and assembled using modular design, which is easy to disassemble and assemble for future maintenance, replacement, and cleaning. The aperture is not less than 5mm.

*9. Temperature control technology: The intelligent artificial climate chamber adopts two sets of valley wheel vortex compressor units for temperature control; The compressor unit is controlled by PLC and can distinguish the required indoor temperature and setting requirements through system logic thinking. It can freely control the number of compressors to switch between working conditions, while meeting indoor problems and achieving energy-saving effects and the service life of the compressor. The compressor unit should also have dust-proof and anti floc configurations to prevent high pressure protection caused by full suction of the condenser. The indoor unit adopts a composite cold air unit, which is designed with dual system temperature control and intelligent defrosting control.

10. Humidity control technology: using an ultrasonic humidification system, the atomized gas is discharged downwards along with the cooling system outlet. The humidifier position sends the moisture into the room through a pipeline, and the inlet is equipped with a filtering device; Dehumidification adopts a refrigerated dehumidification unit and properly handles drainage issues.

11. Fresh air exchange system: using a fully heated fresh air exchange, it can discharge the turbid indoor air while introducing fresh outdoor air into the room. The fresh air volume can reach 400m ³/h.

Supports 8 or more sensor interfaces, 16 or more device control interfaces, and can be connected to a controller. It has a humidification/dehumidification control system (high-sensitivity humidity sensor and controller automatically and manually separate control/room), an environmental temperature control system (high-sensitivity temperature sensor and controller automatically and manually separate control/room), an animal and plant surface temperature monitoring system (high-sensitivity temperature sensor real-time monitoring and recording of animal and plant surface temperature, and can customize automatic alarm function), a lighting control system (controller automatic and manual separate control/room, simulating natural environmental lighting changes), and an on-site video monitoring system (monitoring real-time image data display and recording in the climate room), In the later stage, specific environmental data collection systems can be integrated (such as special gases, toxic and harmful gases, etc. Toxic and harmful gases should include: nitrogen, ammonia, nitrous acid gas, chlorine gas, carbon dioxide, etc.). Each control system can be set to any span to meet the requirements of large-span experimental environments such as temperature and humidity.

13. The control system has a password lock screen function, which prevents unauthorized personnel from entering the operation interface to prevent accidental operation.

14. The system also has alarm functions such as high and low pressure alarm, high and low temperature alarm, and abnormal flow switch alarm. Display text information on the LCD touch screen interface and have a confirm button to release the alarm.

*15. The real-time video monitoring system can record and store the entire process of indoor biological growth in the climate chamber, which can be accessed and viewed later. At the same time, during the monitoring process, a real-time video image of the scene is automatically captured and linked with the on-site environmental data to form a chain system information database. In the later stage, the system can query and retrieve real-time environmental data, on-site image data, and animal and plant morphology image data of a certain period in history. Daily reports of animal and plant growth data are automatically generated and stored, and the reports are automatically cataloged and archived by year and month. The data reports can be stored for more than 10 years, and permission allocation can be made for data viewing. Only authorized users can view the corresponding reports.

16The remote control function can be connected via Ethernet or WIFI, allowing real-time monitoring of indoor temperature, humidity, lighting, and other conditions from anywhere in the world through a computer, tablet, or mobile phone. It can also remotely set the temperature, humidity, lighting intensity, and other parameters that can be set locally in the climate chamber. Free mobile app monitoring software, software upgrades, and cloud services are provided.
